The ability to connect to WiFi network on the iPhone 5 is helpful for a number of reasons. First, it allows you to use large amounts of data, whether by streaming Netflix (Start your Netflix FREE trial today!) or downloading games, without counting against the data on your cellular plan. In most cases it will also provide you with a better and faster connection, which will improve the speed of Web browsing. But, before you can begin to use those WiFi resources, you need to be able to connect to the network, which typically requires a password.
If the password for a WiFi network changes, and it is a network to which you had previously connected, then the stored configuration on your phone will no longer allow you to connect to the network. So you can reconnect by following the instructions laid out below.
Changing a WiFi Password for a Stored Network on the iPhone 5
Fortunately most people do not change their WiFi passwords very often, which is helpful when those passwords can be long and difficult to enter. Plus, when you enter the correct password once for a network on your phone, you will automatically be able to connect to that network when you are in range. But people will change their passwords if they get a new router, if they think that the password is weak, or if an unwanted person has gained access to the network, so it is important to know how to make the adjustment on your iPhone 5.
Step 1: Tap the Settings icon.
Step 2: Tap the Wi-Fi button at the top of the screen.
Step 3: Tap the blue arrow to the right of the network for which you need to change the password.
Step 4: Tap the Forget this Network button at the top of the screen.
Step 5: Touch the red Forget button at the bottom of the screen.
Step 6: Tap the Wi-Fi button at the top of the screen.
Step 7: Select the network that you just chose to forget.
Step 8: Type the new password, then tap the Join button.
When you are once again connected to the network, there will be a check mark to the left of the network name.
